I have a problem with my cougar v6, when it is cold while I press the trotle it suffocates and does not receive power

When I squeeze pedal softer then it reacts normally, but with sudden pressure of the pedal there is a problem

Could be electrical, could be vacuum, could be fuel delivery, could be a clogged air filter, could be the infamous IMRC. We're going to need more details...have you noticed any other issues?

Now I checked, what the imrc sensor should open was permanently opened and jamed by the previous owner, can it stay this way?

Yes, but that's likely why it isn't running correctly. Too much air at lower throttle.

Probably, the last time I drove it, the summer was no problem, now it started when it was colder and it was only the first few minutes while the engine was cold, then everything works normally

Poor performance cold and better warm may indicate an EGR problem.
-Check all the vacuum lines and wiring to the EGR solenoid, EGR valve, and DPFE.
-The two exhaust sensing lines leading to the DPFE can get very brittle and degraded due to the extreme conditions and sometimes need to be replaced.
-You can also clean the EGR passages in the throttle body if you haven't done that already.

Have you checked your OBDII codes if the CEL is on?

IMRC secondary valves pinned open will definitely cause the problem you describe. The engine is expecting MUCH less volume and much higher velocity of intake charge at low RPMs. This is classic IMRC failure.

You need to find yourself a good working IMRC actuator and get those things connected.

Always start with the things you KNOW are broken.
